如何在 div 标签内使用带有 streamlit（bootstrap 卡）的 if 语句

Question

如何在 div 标签中使用 if statement 和 streamlit ？我正在使用 bootstrap card 和 streamlit 来显示来自 dataframe 的信息。我需要的是能够在 bootstrap 卡片 不为空时显示内容，并在其为空时隐藏信息。

代码：

def card(ID,name,nickname,mother_name,bd):

    return f'''

    <div class="card text-center" style="width: 18rem;">

        <div class="card-body">

            <h5 class="card-title">ID: {ID}</h5>

            <h6 class="card-subtitle mb-2 text-muted">Name: {name}</h6>

            <p class="card-text">Nickname: {nickname}</p>

            <p class="card-text">Date of Birth: {bd}</p>

            <p class="card-text">Mother Name: {mother_name}</p>

        </div>

    </div>

    '''
st.markdown("""

df_result_search = pd.DataFrame()
with st.sidebar.form(key='search_form',clear_on_submit= False):
     regular_search_term=st.text_input("Enter Search Term")
     if st.form_submit_button("search"):
         df_result_search = df[df['name'].str.contains(regular_search_term)|df['nickname'].str.contains(regular_search_term)|df['mother_name'].str.contains(regular_search_term)]
                        
                            
 st.write("{} Records ".format(str(df_result_search.shape[0])))
 for index ,row in df_result_search.iterrows():
         st.markdown(card(
                            row[0],
                            row[1],
                            row[2],
                            row[3],
                            row[4],
    ),unsafe_allow_html=True)

Answer 1

我们在显示时使用样式，如果 none 我们隐藏它。结果将最多显示 5 列。必要时打开宽屏模式。

代码

import math

import streamlit as st
import pandas as pd



data = {
    'ID': [1, 2, 3, 4, 5, 6, 7, 8, 9],
    'name': ['peter', 'john', 'james', 'james', 'james', 'james', 'james', 'james', 'james'],
    'nickname': ['pet', 'jon', None, 'james', 'jem', 'jack', 'jo', 'mes', 'ja'],
    'mother_name': ['maria', 'linda', 'ana', 'beth', 'vivian', 'rose', 'meg', 'sharon', 'neda'],
    'bd': ['2000-05-15', '2006-09-12', '2004-10-25', '1999-01-08', '2009-12-14', '2001-11-20', '1999-05-12', '2009-01-28', '2009-03-14']
